From 4 June to 14 September 2026, the Bourse de Commerce - Pinault Collection presents Cloud #07156, a new site-specific installation by Japanese artist Fujiko Nakaya, created for the exhibition Clair-obscur curated by Emma Lavigne.
Installed beneath the Rotunda’s glass dome, the work takes the form of a dense white cloud of water vapour that enters into dialogue with Tadao Ando’s monumental concrete cylinder, turning architecture into an ever-changing atmospheric experience.

Sculpting the Invisible
For more than five decades, Nakaya has worked with fog as a sculptural medium, creating environments that dissolve the boundaries between object, space, and perception. Unlike traditional sculpture, her work has no fixed form: it is shaped by air currents, humidity, temperature, and the movement of visitors.
With Cloud #07156, fog becomes a way of revealing what normally remains unseen. As visibility fluctuates, the installation makes the movement of air perceptible while temporarily obscuring the architecture itself. Space is no longer experienced as empty volume, but as a living field of relationships and transformations.
The work echoes the Japanese concept of ma—the interval or relational space between beings and things—an idea that resonates strongly with the spatial philosophy of Tadao Ando’s intervention within the historic building.

A Dialogue with Architecture
Usually presented outdoors, Nakaya’s celebrated Fog Sculptures have occasionally entered museum spaces, where they acquire a new dimension. In the Rotunda, the cloud interacts directly with Ando’s cylindrical concrete structure, alternately concealing and revealing its geometry.
The encounter is particularly meaningful. Like Nakaya, Ando has long explored the relationship between architecture and natural phenomena, treating light, weather, and time as active components of spatial experience. Here, fog becomes an ephemeral counterpart to concrete: fluid against solid, mutable against permanent.
As the mist drifts through the space, the Rotunda shifts between clarity and opacity, creating what art historian Anne-Marie Duguet describes as a condition where the question is no longer one of viewpoint, but of visibility itself.

An Atmospheric Sculpture
Nakaya often describes her works as “conversations with the wind.” Produced through a sophisticated system of high-pressure pumps and nozzles, the installation generates microdroplets identical in size to those found in natural fog. Although entirely artificial in its production, the cloud behaves according to the same meteorological principles as its natural counterpart.
The title, Cloud #07156, references one of the weather stations nearest to the Bourse de Commerce, linking the installation to the atmospheric conditions of its site and reinforcing its connection to the environment beyond the museum walls.

Architecture as Atmosphere
Born in Sapporo in 1933, Fujiko Nakaya first gained international recognition with her pioneering fog sculpture for the Pepsi Pavilion at Expo ’70 in Osaka. Since then, she has transformed forests, parks, riverbanks, public squares, and museums into immersive landscapes of mist.
At the Bourse de Commerce, her latest intervention continues this exploration while engaging directly with one of the most iconic architectural spaces in contemporary Paris.
Neither object nor image, Cloud #07156 exists as a fleeting condition—a cloud suspended beneath a dome, continuously reshaped by air, light, time, and the presence of those who move through it.
In Nakaya’s hands, fog becomes architecture’s most elusive material: a medium capable of making space visible precisely by allowing it to disappear.
